On arithmetical and dynamical properties of Lorentz maps of the torus [PDF]

arXiv, 2004
We proved that any Lorentz transformation of 2-torus is Anosov automorphism. One completely describes admissible parameters of Lorentz transformations and their arithmetical properties. One proved that an admissible speed light parameter has a countable spectra accumulating to this parameter.

Controlling the Orientation of Polar Axis in Chiral Metal‐Halides to Reveal Their Intrinsic Circularly Polarized Luminescence

Advanced Optical Materials, EarlyView.
In chiral and polar metal‐halide single crystals or thin films, the orientation of the main optical axis normal to incident light allows an easy characterization of the chiroptical properties (circular dichroism and circularly polarized luminescence) without artifacts or macroscopic interferences, despite the highly anisotropic nature in this family of

Three‐Point Functions of Higher‐Spin Supercurrents in 4D N=1${{\cal N}}=1$ Superconformal Field Theory

Fortschritte der Physik, Volume 70, Issue 12, December 2022., 2022
Abstract We develop a general formalism to study the three‐point correlation functions of conserved higher‐spin supercurrent multiplets Jα(r)α̇(r)$J_{\alpha (r) \dot{\alpha }(r)}$ in 4D N=1${\cal N}=1$ superconformal theory. All the constraints imposed by N=1${\cal N}=1$ superconformal symmetry on the three‐point function ⟨Jα(r1)α̇(r1)Jβ(r2)β̇(r2)Jγ(r3)

Regularization of f(T) Gravity Theories and Local Lorentz Transformation

Advances in High Energy Physics, 2015
We regularized the field equations of f(T) gravity theories such that the effect of local Lorentz transformation (LLT), in the case of spherical symmetry, is removed.

Conformally flat Lorentz manifolds and Fefferman Lorentz metrics [PDF]

arXiv, 2009
We study conformal Fefferman-Lorentz manifolds introduced by Fefferman. To do so, we introduce Fefferman-Lorentz structure on (2n+2)-dimensional manifolds. By using causal conformal vector fields preserving that structure, we shall establish two theorems on compact Fefferman-Lorentz manifolds: One is the coincidence of vanishing curvature between Weyl ...

Self‐Assembling Cracks to Fabricate Antireflective Antifogging Metasurfaces

Advanced Optical Materials, EarlyView.
A multifunctional optical device combining antireflective and photothermal antifogging properties is developed by leveraging crack formation in colloidal films. Plasmonic nanoparticle arrays enable localized heating under illumination, while a mesoporous silica coating provides antireflection and water repellency.

Conformal Interactions Between Matter and Higher‐Spin (Super)Fields

Fortschritte der Physik, Volume 71, Issue 1, January 2023., 2023
Abstract In even spacetime dimensions, the interacting bosonic conformal higher‐spin (CHS) theory can be realised as an induced action. The main ingredient in this definition is the model S[φ,h]$\mathcal {S}[\varphi ,h]$ describing a complex scalar field φ coupled to an infinite set of background CHS fields h, with S[φ,h]$\mathcal {S}[\varphi ,h ...

Potential relativistic dispersion in material medium

Results in Physics, 2016
Lorentz space-time transformation has been applied to the phase factor of a plane electromagnetic wave in linear material medium. The derivation shows in the limiting case for v = c, the phase velocity converges to its monochromatic value implying no ...

Susceptibility Invariance and Duality‐Matching Condition for Perpendicular‐Motion Metasurface

Advanced Physics Research
Time‐varying metasurfaces have recently emerged as a promising platform to observe exotic wave behaviors in space‐time systems. In this paper, it theoretically reveals invariant susceptibility parameters for perpendicular‐moving metasurface.
